Different diagrams for the online movie sales
Niles Video Inc. wants to create a website for online sales of movies (DVD and videotapes). People will be allowed to register as customers on the website and to update their stored information. Information must be maintained about customers'' shipping addresses, e-mail addresses and credit cards. In a single sale, customers will be allowed to purchase any quantity of movies. The items in a single sale will be shipped to a single address and will have a single credit card charge.
The website must provide customers the ability to store items to be purchased. When the customer finishes shopping, he will be directed to a checkout area where payment and shipping information is entered. Once the sale is complete, the customer will be sent a receipt by e-mail.
